CARBURETER.

To allwhom it may concern:

Beit known that I, WILLIAM SHEARER, a

subject of the King of Great Britain and Ireland,yresiding at Ferniecotf3 Abbey road,`v,-FJskbank, in the county of Mid-Lothian, V.Scot-land,have invented new and useful 'Improvements in Carbureters, of which thefollowing is a specification.

v My said invention has for its object to improve the construction andaction of carbureters employed in plants making hydrocarbon, petrolized,or air gas in which air is mixed with a hydrocarbon such as gasolene,petrol, and the like, `and then utilized as a gas for illuminating,heating, and like pur poses.

In carrying out my invention the vapo- `rizing surface of the carbureteris arranged so that the hydrocarbon will spread quickly and evenly overa large area, thus completely evaporating the hydrocarbon, and at thesame time distributing the reduction in temperature (due to evaporation)over a large surface. To the reverse or underside of the evaporatingsurface a number of and are immersed in the water or other mediumusually employed to retain the carbureter at a suitable temperature, andby means of those vanes a uniform, or nearly uniform, temperature of theevaporating surface is obtained.`

Means are provided to protect the incoming hydrocarbon, from the air,until such 'y time as it spreads in a thin film over a por tion of theevaporating surface. Means are also provided to distribute the air tothe evaporating surface and at the same time to ive it a swirling motionso as to insure a iorough mixing of the gas or vapor.

In order that my said invention and the manner of performing the samemay be properly understood I hereunto append a sheet of explanatorydrawings to be hereinafter referred to in describin my invention.

Figure 1, is a sectional evation of one example of my invention, andFigs. 2 and 3, are horizontal sections on the lines awt, and C d,respectively, of Fig. l. Fig. 4, is a. sectional elevation of anotherexample, while Figs. 5 and 6, are horizontal sections taken `on thelines e-f, and g-L, respectively, of Fig. 4.

In these drawings the same reference letters are used to mark the sameor like parts wherever they are repeated.

As shown in Fig. 1 of the drawings the carbureter consists'of the usualcylinder or casing, A, within which is arranged a second casing B, theupper' external surface, C, of which is made spherical, .oval or domeshaped, so as to present as great an evaporating surface for thehydrocarbon as is practically possible. The casing B, has arrangedwithin it a series of vanes D, the ob ject of which is to .maintain orequalize the temperature of the evaporating surface, C. The hydrocarbonenters the cylinder or casing A, by the pipe, E, to the evaporatingsurface, C, and a ca o or disk F, protects the hydrocarbon from t eaction of the air until such time as the former has spread in a thinfilm over a considerable portion of the evaporating surface. The airenters by the port, M, and passes through a number of passages, Gr.These passages may be arranged so as to pass the air in one or moredirections. As shown in the drawings these oassages are of substantiallyrectangular form and have wings projecting downwardly therefrom at aninclination, said wings tapering from the inner ends of the passages tothe outer ends. The gas or vapor before reaching the outlet or dischargepipe, H, is intercepted by a number of baffle plates J, so that it isthoroughly mixed before passing from the carbureter. The cylinder orcasing A, of the carbureter is supported on feet, K, to allow ofadequate circulation of the water or other anti-freezing mixture.

As shown in Fig. 4, three casings, B, in the form of spheres, or balls,are employed. These casings, B, are provided with passages, L, so thatwhen the carbureter is placed in a tank or vessel containing theanti-freezing mixture free circulation takes place.

The pipes L (Figs. l and 4) communicate direct with the interior of theinner casing. When the carbureter is placed in a tank containing water,the vaporization of the petrol lowers the temperature of the vaporizingsurface C, transmits the cold to the 'vanes D, and as these vanes areimmersed enters by the pipe, E, and spreads in a thin mixes with the airwhich enters by the port,-

M, and passages G, and is rapidly vaporized. On reaching the baillevplates J, the

gas or Vapor is subJected to a final mixing, afterward passing to thedischarge pipe, H.

vWhat I claim as my invention is:

l. A carbureter comprising an outer casing, an inner casing mountedtherein and provided with a dome-shaped upper end, means for introducingair to the space between the two casings, and for taking the carburetedair therefrom, means for delivering hydro-carbon to the upper surface ofthe dome-shaped upper end, and means for circulating a heating` mediumthrough the inner casing.

2. A carbureter comprising an outer casing, an inner casing mountedtherein and provided With a dome-shaped upper end, means for introducingair to the space between the two Casin s, and for taking the carburetedair there rom, means for delivering hydro-carbon to the dome-shapedupper end, and passages leading from the outer to the inner casing, saidinner casing having an opening in its bottom.

3. A carbureter comprising an outer casing, an inner easing mountedtherein provided With a dome-shaped upper end, means for introducing airto the space between the casings and for taking the carbureted airtherefrom, vanes secured to the inside of the inner casing, means fordelivering hydrocarbon to the dome-shaped upper end, and means forcirculating a heating medium through the inner casing.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses. l
